spark sql 语法问题,新手求指点
使用spark 连接mysql 查询时发现一个错误,经过检测后发现是sql语句的问题,但sql 语句在mysql中是能够查询出来的,但是当使用spark进行查询的时候却发现报错了,sql语句如下: ``` # 计算出支付通道为alipay的金额最大的前5位商户号? select pay_channel,oid,sum(money) from pay where pay_channel = 'alipay' group by oid order by sum(money) desc limit 5 ; select pay_channel,oid,sum(money) from pay where pay_channel = 'alipay' group by oid,pay_channel order by sum(money) desc limit 5 ; ``` 正确代码代码如下,使用的是第二条sql语句 如果使用第一条sql语句是会报错: ``` import java.util.Properties import org.apache.spark.rdd.RDD import org.apache.spark.sql.{DataFrame, Row, SparkSession} object Test23 { def main(args: Array[String]): Unit = { //使用SparkSession.builder.替代SQLContext val sqlContext = SparkSession.builder. master("local[*]") .appName("TestMysql") .getOrCreate() val url = "jdbc:mysql://hadoop01:3306/spark?characterEncoding=UTF-8" val table = "pay" val properties = new Properties() properties.setProperty("user", "root") properties.setProperty("password", "123456") //需要传入Mysql的URL、表明、properties(连接数据库的用户名密码) val df = sqlContext.read.jdbc(url, table, properties) df.createOrReplaceTempView("pay") val frame: DataFrame = sqlContext.sql("select pay_channel,oid,sum(money) from pay where pay_channel = 'alipay' group by oid,pay_channel order by sum(money) desc limit 5 ") val rdd = frame.rdd rdd.foreach(println(_)) } } ``` 此两行sql语句在mysql中都是能正常查出来结果的,它们两个的区别就是第二条sql语句使用pay_channel字段多进行了一次分组,不过我在sql语句中一定把pay_channel作为了一个条件固定死了,为啥还要进行分组,不然会报错,报错内容如下: ``` Exception in thread "main" org.apache.spark.sql.AnalysisException: expression 'pay.`pay_channel`' is neither present in the group by, nor is it an aggregate function.

hive 0.13.1元数据库无法变成mysql
我把hive-0.12升级成0.13.1版本,先在mysql里执行了source upgrade-0.12.0-to-0.13.0.mysql.sql成功了,然后在mysql中创建了一个hivenew(0.12版的是hive)用户,并给予了权限,更改了hive-site.xml文件如下: 1. <property> 2. <name>hive.stats.dbclass</name> 3. <value>jdbc:mysql</value> 4. <description>The default database that stores temporary hive statistics.</description> 5. </property> 6. 7. <property> 8. <name>hive.stats.jdbcdriver</name> 9. <value>com.mysql.jdbc.Driver</value> 10. <description>The JDBC driver for the database that stores temporary hive statistics.</description> 11. </property> 12. 13. <property> 14. <name>hive.stats.dbconnectionstring</name> 15. <value>jdbc:mysql://localhost:3306/hivenew</value> 16. <description>The default connection string for the database that stores temporary hive statistics.</description> 17. </property> <property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:mysql://localhost:3306/hivenew?createDatabaseIfNotExist=true</value> <description>JDBC connect string for a JDBC metastore</description> </property> <property> <name>javax.jdo.option.ConnectionDriverName</name> <value>com.mysql.jdbc.Driver</value> <description>Driver class name for a JDBC metastore</description> </property> <property> <name>javax.jdo.option.ConnectionUserName</name> <value>hivenew</value> <description>username to use against metastore database</description> </property> <property> <name>javax.jdo.option.ConnectionPassword</name> <value>hivenew</value> <description>password to use against metastore database</description> </property> 保存后,把mysql的jdbc复制到了lib下,然后启动hive,虽然能正常显示hive>,和show tables; 但是在mysql里根本没有hivenew这个数据库,我装0.12时装好后自动就有了hive数据库,而show tables,也没有我在hivenew下创建的表格,而且经常出现Caused by: ERROR XSDB6: Another instance of Derby may have already booted the database /opt/apache-hive-0.13.1-bin/metastore_db.这样的错误 可见元数据库仍旧是derby,更诡异的是我把hive-site.xml删掉之后,hive它仍旧工作良好能正常显示hive>,和show tables,难道hive-site.xml的配置都无关紧要吗?求求大家帮帮我,急死人了

推荐一些有趣的在线编程游戏

那些年,我们信了课本里的那些鬼话
教材永远都是有错误的,从小学到大学,我们不断的学习了很多错误知识。 斑羚飞渡 在我们学习的很多小学课文里,有很多是错误文章,或者说是假课文。像《斑羚飞渡》: 随着镰刀头羊的那声吼叫,整个斑羚群迅速分成两拨,老年斑羚为一拨,年轻斑羚为一拨。 就在这时,我看见,从那拨老斑羚里走出一只公斑羚来。公斑羚朝那拨年轻斑羚示意性地咩了一声,一只半大的斑羚应声走了出来。一老一少走到伤心崖,后退了几步,突...
